I Application tiled May 6, 1880. (Nomodel.)

, State `of New'Jersey, have invented a new and following is a description. t

My invention relates to an improvement in dye-tubs, and relates especially to those heated useful Improvement in Dye-Tubs, of which the it consists, rst, vin providing the soft woodwork of the dye-tub with a metallic sleeve, where the connection is made to the coil in the interior, said sleeve bein gpermanently secured in the wood and connected with the coil byV any suitable coupling, so as to be attached and detached at pleasure without breaking any joint in the tender wood; second, in providing a false bottom with a central wooden post, whereby the bottom may be permanently connected with the hoisting apparatus without interfering with the continued use of the tub, the wooden post being free from corrosion by the dye-liquors, and its central position enabling the contents of the tub to be reached and stirred without hinderance; third, in providing the false bottom with a border or guard of flexible material at its margin to prevent thegoods being jammed into the crevice at that point; and, fonrth,lin the employment of a packing around the edge of the false bottom to prevent the articles being jammed initio the crevice at that point.

My invention is designed to obviate the difficulties encountered in the use of the tubs now in common use, .wherein the coil at the bottom becomes clogged or covered with dye-stuffs, thereby preventing the desired radiation of the heat. The tubs in common use are also made square, whereby the convenient stirring and.

tional view of the false bottom and its lifting- V post, and Fig. 6 an enlarged sectional view of the sleeve and union for the coil-joint.

make my tub A round and provide the false' bottom B with a central post, R, to which is attached the rod or chain C, connected with the barrel b of the hoisting-crab. The latter is secured to the adjoining wall or any convenient fixture, andthe rope carried thereto over pulleys E xed overhead. The hoisting-crab is formed with a Worm-gear, g, attached to the barrel b, and a worm, fw, meshing intothe gear and turned at pleasure by a crank, c. Great power is thus secured to lift thc'bottom B and its load of `goods at any time, and the worm forms a self-locking device to prevent the bar- It also serves to holdA the bottom at any desired height in thetub, without the aid ot' other xtures for that purpose. The entire space around the post R is free from obstruction to the stir- Vring of the goods in the liquor, and the whole margin of the tub is equally free from obstructions without and within. The post is preferably made of wood to withstand the dyes employed; and I construct the same with an iron rod, lLthrough the middle,'and .form the rod with-a head, t', at the bottom, resting against an iron washer, u, beneath the center of the false bottom. I also apply a lead cap', a, to the bottom B, over the head t and lwasher a, to

'the top of the post by the cast-iron cap c', and

the post be secured to the bottom B by three or four bolts, with their nuts concealed in the wood of the post, and the heads covered by a lead plate, a, as described above. In such case the cap e would be secured to the top of post. B by bolts in any convenient manner, as they are above the action of the dye-liquor in the tub. Y

In Fig. l is shown a rope, r, attached to the edge of the false bottom by screws and bearing snugly against the sides of the tub to prevent the jamming of the goodsat that point.

A hollow hose may be used instead of the rope, or any suitable material having the requisite flexibility and firmness combined.

By lifting out the false bottom the coil d is exposed, and to permit the ready removal of the same to be repaired, or for cleaning the tub when clogged, I form the coil with joints inside the tub, instead of extending the ends through the side or bottom to connect with the feeding steam-pipe.

To secure a jointinside, and form a connection with the feeding steam-pipef, I fit two sleeves, h, through the side ofthe tub and make each tight in its place by a collar inside and a nut outside,as atm a. The outerend ofthe sleeve is screwed to fit the steam-pipe or its coupling,

and the inner end is fitted to a union, o, applied to the end of the heating-pipe. One sleeve thus serves as an inlet for supplying steam to the coil, and the other as an outlet to drain away the condensed water. By this arrangement a damaged coil can be removed and another replaced in a few minutes without breaking any joints made in the tender wood-work, as is now customary.

The false bottom is shown in the drawings as made of two series of wooden slats crossed upon one another; but my invention has no reference to any particular construction of bottom, and is applicable to any false bottom applied in a tub for the purpose described, and the construction of the union-joints may be modified as desired, without affecting the essential feature of the improvement I have madein attaching the coilto the tub. This consists in fitting the sleeves h permanently into the wood of the dye-tub, so that the coil can be removed bya screw-coupling or union within the tub, and all damage to the wood of the tub be avoided, as well as the delayof breaking and packing a joint in the wood every time the coilis removed and replaced. The wooden post R may also be used without any central rod, I, as the essential feature of the post is its being externally of wood, so as to be little affected by the dyeing-liquids, and its function is merely to lift the false bottom without interfering with the use of the tub in any respect, the combination ofthe central ypost with a round tub affording the utmost facility for stirring and reaching the contents.

I am aware that removable false bottoms are not new, and that they have been provided with lifting devices to elevate them from the tub for the removal of the stock when dyed but such lifting devices have not been permanently connected with the false bottom, because their constructive features would interfere with the manipulation ofthe goods in the tub; and it is only by the use of my central post that I am able at all times to have the false bottom in connection with the lifting 'apparatus, and to sustain the bottom at any desired height in the tub without interfering with the continued use of the tub for dyeing. The capacity of the tub above the bot-tom may thus be reduced to any desired degree, and a small quantity of goods manipulated with great faA cility. I do not, therefore, claim a false bottom in combination with a hoisting apparatus, except the former is permanently connected with the latter to operate in sustaining thev false bottom at any point to which it may be lifted and to lower the same at pleasure.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is as follows l. In combination with the perforated false bottom B,.the wooden post R, constructed substantially as shown and described, and connected to the perforated bottom by rod I, having head or nut i covered by a lead cap,a, the whole combined and operated as and for the purpose set forth.
